TECHNICAL FIELD

The present invention relates to systems and methods comprising liquidcrystal displays and specifically to systems and methods comprisingliquid crystal displays for use as motion sickness management systems.

BACKGROUND

Motion sickness is a well-known malady that often occurs due to exposureto motion in the environment. Motion sickness is likely to occur onboats subject to rolling motion, car travel, train travel, and the like.The symptoms may include vertigo or nausea. There is a wide variationbetween different individuals in sensitivity to motion sickness.Moreover, for those persons affected, the symptoms can range from quitesevere to minimal. There are various prior art theories as to the causeof motion sickness. Some of these theories are discussed hereinafter.

Traditional treatment for motion sickness has relied substantially ontwo primary methods: (1) adaptation, wherein individuals are repeatedlyexposed to a motion environment known to induce sickness, or (2) drugsused to prevent the development of symptoms. Both methods havesignificant problems.

The adaptation method requires weeks (or even months) of exposure timeto the provocative environment. Even after treatment, the individual mayonly be resistant to motion in that specific environment. While the useof drugs for the treatment of motion sickness have significant sideeffects, e.g., drowsiness. Drugs can only be used in situations wherethese side effects are not a factor. In addition, various other remediesare often proposed. For instance, medications and devices are availableoff-the-shelf. Some of these remedies are questionable in theirtreatment ability (meaning that there are no scientific empirical teststhat demonstrate how well these products may work when compared againsta placebo, nor what their effect may be in different motionenvironments).

Research performed by Bles et. al. reviewed the various forms of motionsickness, and redefined the classic sensory rearrangement theory bydemonstrating that only one type of conflict is necessary and sufficientto explain all different kinds of motion sickness. They provide amathematical description from the summarizing statement that “Allsituations which provoke motion sickness are characterized by acondition in which the sensed vertical as determined on the basis ofintegrated information from the eyes, the vestibular system and thenon-vestibular proprioceptors is at variance with subjective vertical asexpected from previous experience”.

Furthermore, research performed more than 20 years ago to investigateadaptation was conducted by having the subjects wear prism glasses thatreversed vision in the horizontal plane (Jones and Mandl, 1981). It wasdiscovered that when wearing these left-right reversing prisms manysubjects would develop symptoms like those of motion sickness. Due tothe variation in persons and motion environments, it was not clear ifthese symptoms would be replicable in actual motion environments. In oneaspect of this testing, it was found that the symptoms were avoided ifthe visual surroundings were illuminated with a brief stroboscopic flashdesigned to provide a 3 μsec view of the visual scene. The flashes werekept brief to avoid any slip of an image on the retina, which istheorized to be related to motion sickness. It was also found thatadaptation occurred during stroboscopic illumination, suggesting thatmechanisms other than retinal slip may be involved in adapting tochanges in the vestibular system. While the results were of interest,the use of stroboscopic flashes, except in the laboratory environment,does not provide a means for controlling motion sickness, even assumingthe results are extended to motion environments.

Manufacturers presently sell LCD shutter glasses wherein the two lenseseach operate independently, typically alternately, in order to produce astereoscopic effect when viewing a computer screen. However, such LCDshutter glasses cannot be utilized to prevent motion sickness, and insome cases, have been found to cause discomfort especially when used forextended durations.

Various theories and devices intended for prevention of motion sicknessare shown in the following patents.

U.S. Pat. No. 6,866,225B2, published on 15 Mar. 2005, to The BoeingCompany, disclose methods and systems for presenting images to vehicleoccupants. A system in accordance with one embodiment of the inventionincludes at least one display portion configured to display an image andbe positioned proximate to a seat location within the vehicle. A firstsignal receiving portion can be configured to receive an input imagesignal, and a second signal receiving portion can be configured toreceive a motion signal corresponding to a motion of the vehicle. Aprocessing portion can be configured to direct to the at least onedisplay portion a time-varying output signal that appears to move byless than an object actually positioned external to the vehicle wouldappear to move to an occupant at the seat location of the vehicle.Accordingly, the viewer may be less susceptible to motion sickness byreceiving visual cues that correspond to less motion than the occupantfeels.

Inorder to effectively prevent or reduce motion sickness, the right amountof motion must be displayed on the image display device when the vehicleaccelerates or turns. Various methods are disclosed for adjusting theimage on the display device and/or the angle of the environmentsubtended to make the motion sickness reduction device effective.

The shutter lenses may be operated ata relatively slow frequency of about 4 Hz when the user is in passiveactivity such as riding in a boat or car or in limited motion situationsin a spacecraft. The shutter lenses may be operated at fasterfrequencies related to motion of the user's head when the user isactive.

All aforementioned disclosures are intended for, and some use verycomplex systems that are not suitable for all types of vehicles.Therefore, there is still a long felt need for a system and methods formanaging, reducing and/or avoiding motion sickness.

The above described prior art does not show the solution provided by thepresent invention. As taught by the present invention, it would bedesirable to provide a system that can be used without training and formore than one user at a time.

DETAIL DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following description is provided, so as to enable any personskilled in the art to make use of the invention and sets forth the bestmodes contemplated by the inventor of carrying out this invention.Various modifications, however, are adapted to remain apparent to thoseskilled in the art, since the generic principles of the presentinvention have been defined specifically to provide a system comprisinga liquid crystal film adapted for treating motion sickness. Thus, anovel method for using such films has been obtained.

The term “about” refers hereinafter to about ±20% of the mentionedvalue.

The term “frequency” refers hereinafter to the number of occurrences ofa repeating event per unit time. It can be measured in mHz (10⁻³ Hz), Hz(10° Hz), kHz (10³ Hz), MHz (10⁶ Hz), GHz (10⁹ Hz), THz (10¹² Hz), andany combination thereof.

The term “phase shift” refers hereinafter to any change that occurs inthe phase of one quantity, or in the phase difference between two ormore quantities in any characteristic of the system or method.

The term “sensor” refers hereinafter to any electronic component,module, or subsystem whose purpose is to detect events or changes in itsenvironment and send the information to other electronics, such as acomputer processor.

Research on the control of sensory function, has suggested thatintegrated information from the eyes, the vestibular system and thenon-vestibular proprioceptors are involved in the occurrence of motionsickness. Specifically related to the information collected from theeyes, retinal slip may be also involved in motion sickness.

The present invention presents visual/vestibular information to thecentral nervous system, which is believed to be a primary factor in thedevelopment of motion sickness symptoms, together with management ofdifferent tools already present in the vehicles and all controlled by asmart central unit connected to several sensors and auxiliary devicesthat allow a more effective and personalized management of motionsickness.

Referring now to FIG. 1 showing a schematic flowchart of the componentsin one embodiment of the present invention. At least one liquid crystalfilm 10 which is retrofitted, mounted, attached, adhered, laminatedbetween glasses or allocated on the windows of the vehicle, is directlyconnected to the Power Dimmer Apparatus 20 which is responsible for theactivation and deactivation of the liquid crystal film. A computer 30comprising at least one processor and a dedicated software is connectedto the Power Dimmer Apparatus 20 and provides the later with theinstructions on the activation and deactivation parameters. A UserInterface Unit 40 in which the user can chose between different modes ofactivation and can chose specific personalization of said modes ofactivation, i.e. the frequency, the level of visibility and the time ofexposure of the activation.

Lastly, connected to the computer 30, a variety of hardware 50 thatprovides further information which is used for the modalities ofactivation of the system. Examples of hardware can be divided in threemain groups:

-   -   1. Already present in the vehicle: like illumination, air        conditioning, entertainment systems, build-in screens, etc.    -   2. Sensors: like light sensor, facial-recognition camera and        software, temperature sensor, etc.    -   3. Adjacent hardware: GPS, navigation systems (i.e. Waze™,        TomTom™, Garmin™, etc.), cellphones, tablets, etc.

In several embodiments of the present invention, the computer 30 usesthe information from said hardware in order to optimize the performanceof the anti-motion sickness protocols. In some embodiments, the computeruses the devices present in the vehicle to facilitate the motionsickness treatment, for example control of illumination.

Any changes in the parameters of the activation of the anti-motionsickness device is characterized by a phase shift, which is any changethat occurs in the phase of one quantity, or in the phase differencebetween two or more quantities in any of said characteristics.

Referring now to FIG. 2, showing a preferred embodiment of the presentinvention in which at least one fast acting, low voltage liquid crystalfilm 10 is placed on the windows of a car 60. However, any vehiclesuitably of having windows, including boats, planes, spaceships, trains,rickshaws, etc., could be conceivably to use the present invention.

Moreover, a single liquid crystal film could be utilized to cover thewhole window or several independent liquid crystal films could be placedon the same window, as shown in FIG. 3, therefore dividing the action ofthe present invention by specific zones.

With regards with the liquid crystal films, several embodiments can beused.

Referring to FIG. 4, in one embodiment, the liquid crystal film 10 canbe simple (a) (one homogenous film) or complex (b-c) (stripes, pixels,etc.).

Referring to FIG. 5, the film can be made of a single film (a) or ofseveral films (b).

In one embodiment, the liquid crystal film can be a solarabsorbing-reflective film, comprising at least one flexible IRreflective transparent conductive film, at least one flexibletransparent conductive film, at least one first layer of liquid crystaldispersions allocated between said flexible IR reflective transparentconductive film or said flexible transparent conductive film and atleast one second layer of liquid crystal dispersions.

In another embodiment, the liquid crystal dispersion is made of nematicliquid crystal mixtures in said liquid crystal dispersion. The liquidcrystal dispersion may comprise cholesteric liquid crystal mixtures,characterized by comprising a broad-band wavelength reflectingcapabilities, in said liquid crystal dispersion adapted to reflectenergy and/or chiral nematic mixtures, adapted to behave as a broadbandcholesteric phase.

The liquid crystal composition can be PDLC, PNLC, PSCT or other.

The liquid crystal is characterized by a liquid crystal dispersionmorphology in polymer matrix of nano-droplets, micro-droplets,macro-droplets or network gel. The liquid crystal dispersion could bemade by phase separation or micro-encapsulation methods.

The liquid crystal is characterized by the possibility of containingdichroic organic and metal-organic compositions.

The liquid crystal film may comprise a pattern, a low-definition displayor a signage.

The liquid crystal film may comprise bi-stable capabilities of theliquid crystal composition.

Thus, the present invention preferably comprises at least one liquidcrystal film, and typically several simultaneously opening/closingliquid crystal films, depending on the number of windows, thatpreferably permit both eyes to simultaneously view the same scene orview or visual information.

However, it is also conceivable that the operating ranges of frequencyand exposure times, as discussed hereinafter, for any of the liquidcrystal films may be different. Thus, alternately or otherwisecontrolling activating and deactivating two different liquid crystalfilms 10 at the operating frequency ranges and/or exposure durationsdiscussed herein may also be utilized to treat motion sickness. In someembodiments, the activation of different liquid crystals issynchronized, with a certain phase shift, so that when one is occluded,the opposite one may be open (and vice versa). This setting is used inorder to minimize the effect of the shuttering on the overall luminancein the vehicle.

In a preferred embodiment, all liquid crystal films 10 operatesimultaneously and in an identical manner with identical timing. In apreferred embodiment, liquid crystal films 10 operate as Motion sicknesscountermeasure. Motion sickness countermeasure 10 is preferablyretrofitted, mounted, attached, adhered or allocated on the windows ofthe vehicle. The motion sickness countermeasure 10 can also be laminatedbetween to glasses. The motion sickness countermeasure 10 can be usedwithout training and in every environment where motion sickness may be afactor. Because no drugs are involved, there are virtually no sideeffects.

While several different environmental factors can induce motionsickness, a common factor associated with every known motion environmentis the concept of sensory confusion or sensory mismatch due to variancein the integrated information from the eyes, the vestibular system andthe non-vestibular proprioceptors. Motion sickness is believed to be theproduct of misinformation arriving at a central point, called the neuralintegrator, in the central nervous system. When information from theears, joints and pressure receptors, and the visual system are all inagreement as to our orientation there is no motion sickness. However,when one or more sensory inputs to the brain is not expected, orconflicts with what is anticipated, the end product is motion sickness.Thus, it is possible to have motion sickness symptoms when theindividual is at rest but the visual environment is in motion(optokinetic).

In almost every known environment that induces motion sickness, there isretinal slip (images that are normally held stationary on the sensorysurface of the eye move) that is caused by a change of gain (adjustment)of the vestibular system. An intact vestibular system is necessary formotion sickness to occur. A product of the change in vestibular gain iseye movements that do not match what is expected in the central locationin the brain. Prevention of retinal slip, and the prevention of sensorymismatch, will reduce the possibility for motion sickness to occur.

Thus, motion sickness countermeasure 10 works to prevent motion sickness(in all types of motion environments) by providing coherent informationto the eyes, the vestibular system and the non-vestibular proprioceptorsand by limiting retinal slip.

Limitation of Retinal Slip

Regarding limitation of the retinal slip, the present invention doesthis by limiting input to the eyes that are brief snapshots of thevisual environment. The snapshots are brief enough that each snapshotfreezes the image on the retina. Motion sickness countermeasure 10 doesthis by using liquid crystal films as electronic shutters retrofitted,mounted, attached, adhered, laminated between glasses or allocated onthe windows of the vehicle. In one presently preferred embodiment, thenominal rate of strobing of the snapshots is kept low, about 3 or about4 Hz.

Exposure time (i.e., the amount of time electronic shutters is clear) iskept short. In one presently preferred embodiment, visual exposure isprovided for each snapshot about ⅓ of the period of the operationalfrequency. The rate of strobing may also be manually controlled, ifdesired. In one presently preferred embodiment, exposure time ispreferably fixed but the exposure time could also be variable,selectable, and/or controllable, as desired. The exposure time ispreferably set short enough to prevent retinal slippage.

In a preferred embodiment, fast response liquid crystal material isutilized in windows whose state from semi-dark to clear can be alteredvia abrupt changes in voltage potentials and/or changes in electriccurrent. The reason why semi-dark is enough, is that the variation inbrightness is enough to freeze the image on the cones photoreceptorswhile allowing to continue the vision on the rods photoreceptors. Thisis important for users that must continue to perform (e.g. drivers)while using the present invention.

Reference now is made to FIG. 6 showing an exemplary comparison betweenthe prior art and the present invention in regards to the relationbetween the frequency and the level of darkness of the liquid crystalfilm. The top graph shows the prior art where the flickering goes from100% visibility to 0% visibility at a certain frequency. The bottomgraph shows how the present invention works. The flickering in thisexample goes from 100% visibility to 50% visibility. Allowing some lightto come through and be perceived by the rods photoreceptors.

It is clear that the percentage of visibility can range from 99% to 1%as necessary by the user. The level of visibility can also be tuned bythe user by means of the power dimmer apparatus and the User InterfaceUnit.

A power dimmer apparatus operative to provide AC current is connected tothe liquid crystal film. The power dimmer apparatus comprises a powerswitch connected in series with the film and a control circuit toachieve proper timing of turning the liquid crystal film on and off,where in order to drive the film, an output AC voltage is applied to thefilm, having at most a very small amount of DC voltage component. Thedimmer is configured as a series connection of two anti-serially MOSFETswitches and is configured as a MOSFET switch connected serially withthe film through a diode bridge. The AC voltage applied to the film isof a quasi-trapezoidal form or a truncated sinusoidal form. Also, the ACvoltage applied to the film has a truncated sinusoidal form which istruncated at a voltage level determined by the control circuit andapplied via the power switch. In general, the maximum voltage levelrating is defined for the liquid crystal film and the power dimmerapparatus has a predetermined maximum voltage level which does notexceed the liquid crystal film's maximum voltage level rating.

In one embodiment, the processor and/or software controlled computer 30or controller device is utilized to control the power dimmer apparatus.

The frequency of operation of the power dimmer apparatus may be fixed orvariable, or selectively fixed or variable, depending on the embodiment.If fixed, the frequency may preferably be about 4 Hz but preferablywithin the range from about 2 Hz to about 6 Hz or preferably at least inthe range from about 0.5 Hz to about 10 Hz. At a frequency of about 4Hz, many slow activity functions can be performed such as being anobserver in a boat or perhaps even operating a boat under manycircumstances. If the frequency is variable, a manual or automaticfrequency control may be provided. If manual, then the control may beswitchable or continuously variable. As activity becomes faster, thenthe frequency of operation may be increased. For instance, frequenciesfrom about 25 Hz to about 50 Hz may be utilized to accommodate a user ina quick motion or faster activity operation, e.g., driving in a trafficroad, although a preferred upper limit of frequency may be about 40 Hz.

As mentioned before, not only the frequency can be changed by the user,but also the level of visibility can be adjusted by the user. This allowusers who have problems with night vision, and therefore have problemswith their rod photoreceptors, to adjust the percentage of visibility totheir needs, without losing the anti-motion sickness effects andpermitting the continuation of the driving performance. Alternatively,the computer automatically chooses the contrast between open and closedsates, according to the ambient illumination. When the ambientillumination is high (such as in broad daylight), the contrast betweenstates will be lower, and when the ambient illumination is low (such asnight time), the contrast between sates is set to be higher.

In one preferred embodiment, the duration of exposure is 5 milliseconds.In any event, the exposure timing will preferably be significantlyshorter than the period of operation of the liquid crystal film. Thus,in one preferred embodiment, the exposure timing is less than one-halfthe period of operation of the liquid crystal film but could be smalleras desired, e.g. in another embodiment the exposure timing may be atleast four to five times shorter than the period of operation of theliquid crystal film The exposure timing should be in the range of valueswhereby the image is exposed to the retina long enough to sense theimage but quickly enough so that the image does not move an appreciableamount over the retina.

In operation, the use of windows for the prevention of motion sicknessis quite simple. As explained above, the liquid crystal film on thewindow preferably function by darkening for brief moments at a desiredrate (from about 4 Hz to about 40 Hz) to permit the user to view thevisual environment while simultaneously preventing image slip on theretina.

In one preferred embodiment, the liquid crystal film has three basicmodes of operation as discussed subsequently. However, as explainedearlier, there are many possible variations of operation.

OFF-Mode is a static mode that clears the liquid crystal film making itpossible to see through the windows.

ON-Automatic Mode activates the liquid crystal films at a standardfrequency of about 4 Hz and frequency adapts automatically as the speedof moving changes.

ON-Fix Mode activates the liquid crystal films at a standard frequencyof about 4 Hz.

ON-Manual Mode activates the liquid crystal films at a frequency chosenby the user.

Safety of the present invention requires that their use be limited tothose individuals who are not sensitive to epileptic seizures.Photosensitive epilepsy is the name given to that form of epilepsy inwhich seizures are provoked by flickering light that is encountered ineveryday life. Photosensitive epilepsy is rather rare. About one personin every 200 is diagnosed as having epilepsy. Out of these only oneperson in every 10,000 has photosensitive epilepsy. The age of onset forphotosensitive epilepsy is usually between 9 and 15 years. Girls aremore sensitive than boys. It is rare to have onset sensitivity beforethe age of 5 or after the age of 20. Most individuals are aware thatthey suffer from this type of epilepsy and therefore, it is relativelyeasy to screen for those that have photosensitive epilepsy. Triggers forphotosensitive epilepsy include: (1) viewing a television screen (mostcommon), playing a video game, or computer graphics; (2) a light sourcethat flickers at a low frequency; (3) sunlight coming through a line oftrees; (4) sunlight on water; (5) looking out a train window; (6)stroboscopic lights; and (7) looking at a moving escalator. Even thesetriggers are not all positive for induction of photosensitive epilepsy,and require a number of other factors: (1) frequency of the lightstimulation; (2) light intensity; (3) background illumination; and (4)wavelength of the light. And usually, people with photosensitiveepilepsy have had seizures both with and without flashing (flickering)light. While sensitivity varies as a function of flash frequency, it hasbeen determined that 96% of people with photosensitive epilepsy aresensitive to light flashes from about 15 to about 20 Hz.

To reduce the possibility that motion sickness countermeasure 10 willinduce photosensitive epilepsy in susceptible individuals, the basicflash rate of the liquid crystal film is preferably less than about 4 Hz(a frequency where there is little or no likelihood of inducing anepileptic episode, and taken with adherence to the following screeningcriteria should preclude any safety issues). Thus, those persons withthis disability may use motion sickness countermeasure 10 in ON-ManualMode, or in an embodiment which only operates as per ON-Fix Mode, whichis the basic 4 Hz estimated rate. Advice of a physician should also beobtained for those persons.

Additional warnings would suggest that motion sickness countermeasure 10should not be used by any individuals who have been diagnosed with anyform of epilepsy unless under the care of a physician. Other persons whoshould obtain advice from a physician before use are persons' in whosefamily there is a history of epilepsy. Additionally, anyone who has everhad an adverse reaction of any kind to stroboscopic illumination, anyonewho has ever had a neurological seizure of any kind, anyone who has everdisplayed or experienced episodes of blank staring, twitching of themouth or face, jerking movements in other parts of the body, theinability to talk or respond, or sensory hallucinations, and anyonetaking any of the medications, or has ever taken any medications thatare used to treat epilepsy should not use motion sickness countermeasure10 unless under the supervision of their physician. These drugs includeCarbamazepine (Tegretol, Tegretol-XR, Carbatol), Ethosuximide(Zarontin), Gabapentin (Neurontin), Lamotrigine (Lamictal)Phenobarbital, Phenytoin (Dilantin), Tiagbine (Gabitril), Topiramate(Topamax), Valproate (Depakote), and Sodium Valproate (Valproic Acid).

One advantage of the present invention is that the system can affectmore than one passenger at a time, saving costs in individual personaldevices. Another advantage of the present invention is that each liquidcrystal film can be personalized in their action modality independentlyof the others. With regards of more films per window, each film can alsobe personalized to the needs of the different users (e.g. driver andnear-driver passenger).

Providing Coherent Information to the Eyes, the Vestibular System andthe Non-Vestibular Proprioceptors

Research shows that the least affected person of motion sickness isusually the driver. Several reasons suggest that this is due the factthat the driver's whole mind and body are occupied with the action ofdriving. Initiating with the mind, the driver knows where the vehicle isgoing, therefore the body (non-vestibular proprioceptors) knows toprepare for the future movements of the vehicle (affecting thevestibular system). The wide-angle undisturbed vision of the driver (theeyes), provides him with the tools to understand its position inrelation to the exterior, giving him a complete sense of what ishappening while driving.

It is obvious that all the passengers cannot drive the vehicle.Therefore, there is need to complement the passengers with the requiredinformation regarding the current motion and the future paths of thevehicle.

The present invention provides this information in several ways:

Driving directions on the windshield/build-in screens: in the case ofliquid crystal films manufactured with pixels, almost any image can bereproduced. Referring now to FIG. 7, reproduction of the driving path 80on the front windshield 70 and/or on the build-in screens, will providethe necessary information to the passengers about the current and futuremovements of the vehicle.

Providing an artificial horizon: since in each window there is a liquidcrystal film 10, an artificial horizon can be reproduced. Referring nowto FIG. 8 showing different embodiments of this feature. On the leftside from top to bottom, (a) a continuous fixed line is reproduced onthe window. Optionally two lines (b) can be reproduced. In case thevehicle is going downhill (c) or uphill (d), the line can be reproducedin a diagonal matter. This feature can be further controlled by adigital/analog tilt gauge connected to the computer 30. In anotherembodiment, the line is not continuous, but is a dotted or dashed linethat “runs” on the window depending on the velocity of the vehicle(e-h). In yet another embodiment, the line can be continuous vertical(i) or not-continuous vertical (j). In another embodiment, the use ofgeometrical forms may be used (e.g. square, circle, triangle in k.) or avariety of waves (l). It will be obvious to a person having an ordinaryskill in the art, that variations of displays can be generated using theliquid crystal film, and there is no need to attempt showing them all.

In some embodiments the “artificial horizon” feature acts just as a realartificial horizon would, showing the direction of the car relative tothe horizon (slanted sideways, up or down). In some embodiments the“artificial horizon” acts differently than an artificial horizon would,and shows information on where the car is accelerating to, i.e showingthe vectors of force acting. In these embodiments, the artificialhorizon may move even when the direction of the orientation of the cardoes not. For example, when accelerating down a slope, the artificialhorizon might continue moving up, even if the slope is constant.

Peripheral Vision

It has been extensively studied the differences between central visionand peripheral vision. FIG. 9 shows the distribution of the vision inhumans (By Zyxwv99—Own work, CC BY-SA 4.0,https://commons.wikimedia.org/w/index.php?curid=37052186). Furthermore,in a study published by Stephen et. al., it was shown that both centraland peripheral visual stimulation initially activates similar areas inthe brain, the information from central versus peripheral fields ofstimulation arrives in the higher visual areas via different routes.That is, peripheral information has access to fast, direct pathways thatallow for faster onset times in dorsal stream areas. In addition,sustained activation occurred in dorsal stream areas of the brain inresponse to peripheral stimuli, while activation in dorsal streamstructures evoked by central field stimuli subsided. This suggests thatnot only is the dorsal stream important for determining stimulusmovement and location in space, but also monitoring peripheral stimuliin general. The results of that paper suggest that within the dorsalstream there is a timing division between information received fromcentral and peripheral visual fields.

Using this information, the present invention discloses a novel andunique method of delivering proper stimuli (information) with regards ofmovement and artificial horizon to the peripheral vision of passenger.This enables the passenger to use the central vision for recreationalpurposes (reading a book, watching a movie, etc.) while at the sametime, the system delivers information through the peripheral vision,diminishing substantially the possibility of motion sickness.

It is well known that the peripheral vision is of much lower resolutionthan the central vision, making presentation of information to theperipheral vision extremely challenging. The current invention describesmeans and methods of providing information to the peripheral vision, bymeans of large light effectors embedded in the windows of the vehicle(or projected on large surfaces in windowless vehicles). These visualcues are specifically designed to suite the peripheral visual system.The system uses flashes (known to reduce the threshold stimulationneeded for detection and attention), large images (to accommodate forthe low resolution of the peripheral system), and high contrast (goingfrom transparent to opaque). It is a scope of the present invention toprovide a system that adapts the visual cues, so that they can bemeaningfully perceived by the peripheral system that is notoriously lowresolution system. For this, the invention uses large simple movingshapes, with movement and flicker that increases their perception by theperson in the vehicle.

Furthermore, the system is adapted to identify the peripheral visionareas of each one of the passengers. As shown in FIG. 9, those areas arefrom about 30 degrees to about 110 degrees apart from the center of theeye.

In one embodiment of the present invention, the system comprises acamera 90 installed inside the vehicle. The camera is connected to thecomputer 30, which is equipped with dedicated facial recognitionsoftware, as shown schematically in FIG. 10. The system recognizes notonly the faces of the passengers 91, but also the inclination and thedirection of the heads, also known as gaze. Since it is known thatpassengers that have access to “real horizon” suffer less of motionsickness, the system activates and deactivates the anti-motion sicknessprotocol depending on the direction and inclination of the head of eachpassenger. In some embodiments, the systems turns itself OFF when thegaze of the passenger is fixed directly at a side window. In someembodiments, the systems turns OFF only part of the system, the windowcorresponding to the gaze of the passenger.

In several embodiments, the system comprises at least one sensoroperative to sense the directionality of the gaze of each one of thepassengers. Therefore, the system is adapted to use said directionalityof the gaze and the identified peripheral vision areas determine how toactivate or deactivate the liquid crystal film In some embodiments, thesystem can activate the film in some windows and deactivate in others.Also, the system is capable to modify the way the film is activated inorder to keep stimulating the peripheral vision only, by keeping theactivated parts of the film in specific peripheral vision areas of eachpassenger.

In some embodiments, the system anticipates a motion sickness inducingcar motion (such as an approaching curve), and activates the system toalleviate the anticipated motion sickness.

In some embodiments, the system anticipates a motion sickness of thepassenger, depending on the gaze of the passenger, anticipating motionsickness when the gaze of the passenger is fixed on an object in thecar.

In some embodiments, the system adjusts (tilts) the artificial horizonaccording to the sensed inclination of the passenger's head, so theartificial horizon remains parallel to the direction of gaze (and/orsimulating a simple forward movement in the direction of gaze).

In some embodiments, the cabin illumination apparatus (i.e. internallight) is timed to the window flickering, and is set to offset theeffect of the flicker on the cabin illumination. In these embodiments,the illumination intensity is increased when the window is shut anddecreased when the window is transparent. The adaptation of the lightingin the car minimizes the “side effects” of the window flicker. The “fullcar flicker”, that is visible to the central vision, is avoided byadapting the contrast of the window states and by manipulating the cabinlighting.

In several embodiments of the present invention the system providesstimulations only to the peripheral visual field which are invisible tothe central vision, unless the head is turned directly towards thewindow. It is known that even if stimulations are somehow perceivedindirectly by the central visual field and directly by the peripheralvision field, does not mean that the person is actively noticing saidstimulations. Therefore, it is a scope of the invention to present asystem that minimize the (indirect) effect on the central vision, andmaximize the utilization of the peripheral vision.

EXAMPLES

In all the examples below, the system may respond to real time sensedparameters or anticipate the movements described, based on acomputerized navigation system.

In cases stripes are used, the width of the stripes may vary from 3 cmto 15 cm.

The examples below describe response to relatively simple motions, forthe sake of example. The actual operation of the system may incorporateone or more of the effects below, in response to one or more vectormotions sensed at a particular time. Images may be superimposed on eachother, or combined.

-   -   1) The car is driving forward on a straight road—accelerating:        the passenger may experience a mismatch between his visual        system (fixed on a book) and his proprioception systems        indicating acceleration. In order to minimize this conflict, the        system will show vertical stripes moving across the side        windows, at an accelerating rate. The person will notice these        large and possibly flickering stripes with his peripheral        vision, and thus the mismatch is minimized    -   2) The car is driving forward on a straight road—decelerating:        the passenger may experience a mismatch between his visual        system (fixed on a book) and his proprioception systems        indicating deceleration. In order to minimize this conflict, the        system will show vertical stripes moving across the side        windows, at a decreasing rate (speed). The person will notice        these large and possibly flickering stripes with his peripheral        vision, and thus the mismatch is minimized    -   3) The car is “free falling” (a sudden down slope of the road):        the passenger may experience a mismatch between his visual        system (fixed on a book) and his proprioception systems        indicating a fall. In order to minimize this conflict, the        system will show an artificial horizon that moves upwards,        mimicking the view of an actual fall. The person will notice the        large and possibly flickering rise of the horizon with his        peripheral vision, and thus the mismatch is minimized    -   4) The car is “lifted” (a sudden upwards bump or slope of the        road): the passenger may experience a mismatch between his        visual system (fixed on a book) and his proprioception systems        indicating a “jump”. In order to minimize this conflict, the        system will show an artificial horizon that moves downwards,        mimicking the view of an actual jump. The person will notice the        large and possibly flickering rise of the horizon with his        peripheral vision, and thus the mismatch is minimized\    -   5) The car takes a sudden sideways acceleration (i.e side wind,        jolt of the wheel, etc.)—the system may show a rapidly        increasing shape (a triangle for example), to mimic view of an        actual movement towards the corresponding window    -   6) Combinations—if the car is accelerating downhill, the system        may choose to show accelerating horizontal stripes, that do not        cover the entire height of the window. The end of the stripes        will act as the artificial horizon and move upwards accordingly.        Etc.    -   7) The car is taking a strong curve to the right—the system may        choose to show vertical stripes traveling across the side        windows, with the stripes on the left being more spaced from        each other and traveling at a lower speed in comparison to the        stripes on the right.    -   8) A passenger is sitting in the middle of the back seat of a        vehicle, looking forward at the road. Assuming the passenger is        sitting about 30 centimeters from a side window, the system        activates the liquid crystal display to a maximum of root 3×30        in order to remain within the 150 degrees of the peripheral        vision.

In some embodiments, the stripes described are made by a stripe ofocclusion, in some embodiments the same stripes are achieved by leavinga transparent stripe, while the rest of the window is occluded (or lesstransparent).

Flickering of the window might disturb people outside the vehicle, likeother drivers, pedestrians, etc. In another embodiment of the presentinvention, flickering of the window is hide by using multiple layers offilms, as shown in FIG. 11. Liquid crystal film 100 is the external filmthat anybody from the outside will see. After liquid film 100, therewill be a second liquid crystal film 101 that will have a “bright”color. Finally, the third liquid crystal film 102 will be used toprovide the stimuli necessary to treat or avoid motion sickness. Thisorganization of several liquid crystal films enables the film 102 toactuate on the bright background provided by film 101. All these stimuliare hidden from the outside world by film 100 that is dark.

Using a Well-Known Scale

In order to evaluate the efficacy of the system, motion sickness isinduced in subjects using a driving simulator 200 (e.g. NADS-1 of TheNational Advanced Driving Simulator of the University of Iowa,https://www.nads-sc.uiowa.edu/sim_nad1.php), as shown in FIG. 12.
